Overview
Antioch builds high-fidelity simulation tools for physical AI and robotics teams. It announced a $32 million Series A led by Greylock in September 2026, funding simulations designed to reproduce customer hardware conditions. The company named Amazon's Ring as a customer but did not publish its valuation or recurring revenue.
Why Antioch is interesting
September 8, 2026: Greylock led a $32 million Series A. The company says teams can run thousands of parallel evaluations in hardware-calibrated simulation before physical deployment. Named customer: Amazon’s Ring (press release). Valuation, ARR, and paying-customer count were not disclosed. Seed was $8.5 million earlier in 2026; Robot Report put a 2025 pre-seed at about $4.24 million — do not add the three prints into a company total without a company figure.
Product & use cases
Cloud simulation for robotics and autonomy: calibrate a digital twin to the customer’s hardware, then run many parallel evaluations before real-world deployment.
- Robot and drone policy evaluation before hardware time
- Industrial automation and fixed-perception test coverage at cloud scale
Key facts
- Sep 8, 2026: $32M Series A led by Greylock (company / Greylock post); no valuation
- Named customer in the release: Amazon’s Ring; quote from Ring CPO Jason Mitura
- Seed $8.5M earlier in 2026 (Robotics 24/7); pre-seed ~$4.24M (Robot Report) — totals conflict if summed
- BoxGroup participated; directory fund page exists.

Competitive landscape
Edge: The diligence question is whether hardware-calibrated cloud sim actually cuts physical test hours — Ring is a named logo with a held-out-test quote, not a revenue figure.
Antioch sells simulation. XDOF sells real-world teleoperation data. Atoms is a physical-AI holding company. Do not treat a $32 million Series A as a substitute for those other prints.

NVIDIA Isaac Sim / Isaac Lab adjacent
Company says it integrates NVIDIA’s open stack. That is a partnership claim, not an acquisition.

Real-world robot data collection, not a simulator. See /startup/xdof.

Forbes framed Antioch against Figure’s real-world video collection spend. Different product.
